SPECIFICATION forming part of Letters Patent No. 309,620, datedDecember23, 1884.

Application filed Api-i127, 1883. (No model.)

.To @ZZ whom t may concern:

Be it known that I, JOHN Hausimiv, a citizen of the United States,residing at Newark, in the county of Essex and State of New Jersey, haveinvented certain new and useful Improvements in Dies for Hammers; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to letters of reference markedthereon, which form a part of this specification.

This invention relates to an improved means for forming hammers, andmore especially those used by machinists.

The invention consists in such relation and construction of parts asWill be hereinafter set forth, and finally embodied in the claim.

In the drawings, in which similar letters of reference indicate likeparts in each of the several figures, Figure l is a plan view of a lowerdie with a hammer therein. Fig. 2 is a plan of the under side of theupper die. Fig. 3 is a vertical section of the dies together with ahammer between them. Y

In forming a hammer completely in the ordinary man ner and with theusual means there is a great deal of labor required, the tool passingthrough many hands and operations during the process.

By the use of my improved die the hammer is struck out in the dies andneeds only to be trimmed and ground to complete the op eration, thuseffecting a great saving in time and consequently in the cost ofproduction.

Referring to the accompanying drawings, A is the upper die; B, the lowerdie, the depressions in the dies being counterparts one of the other.Said depressions when united or brought together conform to the shape ofan ordinary machinists hammer, as indicated in the drawings, and havewithin each a punch, a, rising flush with the surface ofthe dies. Sai dpunches taper toward the top or meeting surfaces of the dies. Thepunches are inserted through the outer faces of the dies and backed upby a metal plug, b, as indicatedin Fig. 3; or said punches may extendthrough the dies, the plug being dispensed with. rlhe punches, ifdesirable, may be inserted in the upper surface and screwed or otherwisesecured therein. I make the punches removable, so that they can be takenout when worn by use, thus increasing the length of service ofthe dies.

By means of having the punches tapered to the center, as described, theeye is much easier formed, the tendency being to press a portion of themetal toward thesides in every direction, instead of all toward thecenter. Moreover, after the swaging is completed the removal of the diesfrom the hammer is for the same reason very greatly facilitated, itbeing done without any difiiculty. Besides, the shape of the eye thusformed by the tapering punches is such that the securing of the handletherein is also facilitated, as it can be done without specialpreparation of either the eye or the handle for the purpose, as will bereadily understood.

VIn forming a hammer a given portion of a round bar of steel suitablyprepared by being partially iiattened, andthe end that is to form theball ofthe hammer reduced in diameter,

is placed between the dies, and a few succes sive blows struck until thedies come nearly together, thus forming the eye and body of the hammerat l'the same time. The hammer is then passed through a trimmer,removing the burr around the tool, and the web d, Fig. 3, punched out.After being trimmed it is cut from the bar and ground, and another givenportion of the bar prepared as before, and the operation repeated.

I am aware that dies for forming hammers and provided with punches forforming the eyes therein are not new, and I do not claim the same,broadly, but,

Having thus described my invention, what I claim as new is- Theherein-describcddie for making hammers, consisting of the twin dies Aand B, each of which is provided with correspondingly similarprojections and recesses, and each also provided with a removable punch,tapering toward the face of the die, in which it is se' cured, and tlushwith said face, each die constructed to facilitate the insertion andremoval of said punches through that side of the die which is oppositethe side which impresses the metal, all substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand this2d day of April, 1883.
